Screaching from behind balancer

I had this with the double roller I installed in my LA. when torqued the balancer snout sandwiches the slinger. If the chain links and pins are wide enough they rub the inner surface of the slinger during rotation ,making a pretty "spirograph" (how old am I)pattern etched into the tin and plenty of squeal. You can try shimming but the pulley grooves will be out of alignment by the time your done.Proofs on my bench, I've also run across the lower water pump bolts being replace with to long of a bolt and rubbing the cam gear. Good luck sir.
